Which security threat occurs when a developer leaves an unauthorized access interface within an application after release?

The security threat that arises when a developer leaves an unauthorized access interface within an application after its release is referred to as a persistent backdoor. This type of security threat allows unauthorized users to gain access to the application or its underlying systems without the need for standard authentication mechanisms. Persistent backdoors are particularly concerning because they can remain undetected for long periods, providing a point of entry for attackers and potentially leading to data breaches or unauthorized manipulation of application functions.

In contrast, deprecated APIs refer to programming interfaces that are no longer recommended for use but may still exist within the application. While they can pose security risks if not removed, they do not represent the same kind of intentional access point as a persistent backdoor.

An Easter egg is generally a hidden feature or message within the software, which is not malicious and is usually included for fun or as a joke by the developers. It does not typically pose a security threat but could be misused if it reveals sensitive information.

Development operations (DevOps) encompass practices aimed at combining software development and IT operations, which is not directly related to unauthorized access or vulnerabilities within the released application.

Understanding how persistent backdoors can be introduced during the development stage helps reinforce the importance of robust testing, code reviews, and security
